[refpolicy] [PATCH v3 5/5] rtkit: enable dbus chat with xdm

[guido@trentalancia.net (Guido Trentalancia)]

Enable dbus messaging between the X Display Manager (XDM) and
the rtkit daemon.

Also, let the rtkit daemon set the priority of the X Display
Manager (XDM).

This patch (along with parts 3/5 and 4/5) might be needed when
running gdm.

I do apologize for the broken interface in the previous version
of this patch.
